My fiancé (M23) and I (F21) have been together for 3 years. We knew when we first meant that we wanted to be with each other and build a future and family together. However, he told that he wants to be with me forever BUT sleep with different girls here there because he says it’s not possible he could just be just me. Although I did agree to it at first but then I kept putting thought into it and had told him I was not okay with. Which I take solely 100% blame for bc I had said yes but changed my mind. But he is upset that I said yes and then no because he says I lied. We have had this ongoing issue for a while because I’m still not okay with it but I told him I very much down for a threesome because I want to experience being with a girl. But he said that I’m a liar since I’m not okay with him sleeping with girls alone but okay with having a threesome. As I explained to him it’s bc I will be there as well, and that both of us would be having fun. I asked him if I had said no the first about him being able to sleep with other people what would we do then? And his response is that “we would figure it out” but we aren’t even doing that right now. He’s also on Instagram and was on tinder just talking to girls but Instagram he gets upset when I see messages he sends to other girls. He says that girls and guys can’t be friends but he is doing so himself.

I love him very much and have envisioned my whole life ahead me with him. As for him he said that if we break up, he’ll be the same with every other girl. I’ve tried talking to him about how I feel ab him doing what he wants and leaving a door open for these girls to come into his life impacts how we are going to be bc when I bring how uncomfortable it makes me he assumes it’s the girls that make me upset and not realizing it’s him doing something that I’ve said bothers me. He doesn’t want to break up and wants me to tell him what what I think but doesn’t want to work on what I had an issue about.

Just wanted to know how we could go about this? Is there anyway for us to work this out or are the signs clear enough we just are not for each other?
